The lithium ion batteries hold a charge for a long time. The one I use for a jump pack can sit unused for 6 months and only lose between 4-6%. I check and top it off every 6 months or so. I don't think topping off liion batteries is a bad thing. I don't carry power tools as a matter of course. That's what the ratcheting breaker bar is for, 18" of breaker with 18" of cheater is more than enough to break loose the lugs and the ratcheting makes jacking easy enough by hand without all the extra bulk. Like I said, everything except the jump pack and tool kit fits with the spare and those fit in the expandable storage which leaves the trunk 80% empty.Yeah, the impact wrench--I'd go half-inch instead of quarter--is a good idea, but the one advantage of the electric jack I have is that it works off the car battery, which is (presumably) always charged. I think even lithium batteries self-discharge over time--I may be wrong, I use and charge mine regularly--and you could have a dead battery when you need it (unless you pull it out and dis/charge it regularly, I think 'topping off' Li-ion batteries may not be good for their lifespan). Of course, impact wrenches are great for spinning lug nuts off and on, but even my DeWalt 20V half-inch won't put the full 150lb-feet on the nuts.
It works for me...
